Joy St Clair Hester (31 August 1920 – 4 December 1960) was an Australian artist.
She was a member of the Angry Penguins movement and the Heide Circle who played an integral role in the development of Australian Modernism.
Hester is best known for her bold and expressive ink drawings.
Her work was charged with a heightened awareness of mortality due to the death of her father during her childhood, the threat of war, and her personal experience with Hodgkin's Disease.
Hester is most well known for the series Face, Sleep, and Love (1948–49) as well as the later works, The Lovers (1956–58).
